INGANDESCENT GAS-BURNER.

Specification of Letters Patent.

Application filed April 26, 1917. Serial No. 164,702.

To all whom it may concern: Be it known that I, J ULIEN OAYRoL, c1t1- zen of the French Republic, residing at Paris, 114: Rue de Grenelle, France, have invented new and useful Improvements in Incandescent Gas-Burners, of which the following is a specification.

My invention has for its object an improved burner for incandescent gas lighting. The particular object of my invention is to so construct the burner that the volume of the gas may be regulated independently from the pressure in the gas supply pipe, a

means also being provided controlled by the pressure of the gas.

My invention is shown on the accompanying drawing: in which,

Figure 1 is a sectional elevation of my burner, the section being taken through the axis of the burner.

F ig. 2 is a sectional plan, the section being on the line II-II in Fig. 1.

Figs. 3 and 4 show respectively in elevation and plan, on a larger scale, the special means for obstructing the passage of the gas.

The means for regulating the flow of the gas comprises a nozzle a which is threaded into the sleeve 6 formed at the bottom of the chamber 0 where air is admitted throu hthe slots ol, to mingle with the gas rising 1n the mixing tube e. The nozzle 6; contains within its lower end a the regulating means.

A valve contained in the nozzle a can be displaced therein by means of inclined screws 7. This valve comprises a cylindrical body 9 having vertical grooves g and provided at its lower end with a collar 9 on which bears a helical spring h the upper extremity of which bears against a shoulder a in the nozzle a. The latter is closed at its upper end by a cover 2', having a central aperture 2' through which the gas is admitted to the chamber 0. This aperture 71 can be partially or wholly closed by the conical head 9 of the valve 9 as thelatter is raised or lowered by means of the screws f.

Then the screws 7'' are completely withdrawn into the wall of the nozzle a, the valve 9 will descend by gravity, assisted by the spring h, against an arresting abutment y'.

Patented Dec. ill, Milt.

Should the central aperture 2' become clogged, the screws 7 can be manipulated in such a manner so as to force the extremity of the conical head of the valve 9 repeatedly into the said aperture thus efi'ectively cleans ing it.

Into the lower end of the nozzle a, is screwed aconnecting piece 70 which, in turn, can be screwed onto the gas supply pipe. This piece 70 carries a horizontal partition m provided with perforations n. The parti tion we carries a vertical stem 0 adapted to guide the valve represented in detail in Figs. 3 and l. This valve comprises a disk 9 formed on the lower extremity of a socket q, the upper end of which forms a pointed arch and is provided in its center with an orifice 1-. According to the pressure of gas, the

valve 39, q will be more or less raised, and thus project more or less into the tubular part k of the member is, thus regulating the flow of the gas.

I claim asmy invention:

In an incandescent gas burner, the com bination with a loose plug valve controlling the orifice in said burner, and means for raising the plug valve to more or less project into said orifice, of a connecting piece havmg a neck portion screwed into the lower part of the burner and a perforated horlzontal partition, a central vertical stem projectname to this specification in the presence of 1 two subscribing witnesses.
